适用场景

• NetApp SANtricity OS 11.70.1.GA 之前的版本
• 即时可用格式（ Immediate Available Format ， IAF

问题描述

• 此时将创建一个卷并将其映射到主机。

A:7/18/21, 9:56:26 PM (21:56:26) 2713 520f Create volume-to-LUN mapping - Volume 1
A:7/18/21, 9:56:10 PM (21:56:10) 2712 5023 Controller return status/function call for requested operation - Shelf 99, Bay A
----> RPC function : 0x0007 = createVolume
----> Return code  : 0x0001 = ok
A:7/18/21, 9:56:10 PM (21:56:10) 2711 5002 Create volume - Volume 1
